WebSuspended Solids, Wastewater TSS testing measures the total concentration of suspended (non-soluble) solids in the aeration stabilization basin (ASB) or in effluents. The total suspended solids (TSS) data is critical in determining the operational behavior of a waste treatment system. WebWe can calculate the concentration of O 2 (aq) to be 0.00027 M. Typically, BOD is measured in mg/L or in percent saturation rather than mol/L. Percent saturation is the amount of oxygen in a liter of water relative to the total amount of oxygen that the water can hold at that temperature.
